Which type of cyst forms where a tooth should have developed but is missing?

• A. Periapical cyst
• B. Primordial cyst
• C. Radicular cyst
• D. Follicular cyst

Answer: (B)

A primordial cyst forms in the location where a tooth should have developed but is missing. This type of cyst arises from remnants of the enamel organ, indicating that the tooth did not form during development, leading to the cystic structure in its intended location. Primordial cysts are often found in younger individuals and can be associated with odontogenic processes. In contrast, periapical cysts occur at the apex of a non-vital tooth, typically resulting from pulp necrosis. Radicular cysts are similar, arising from the same processes but are more specifically associated with the root of the tooth after the tooth has erupted. Follicular cysts, on the other hand, form around the crowns of unerupted teeth, such as wisdom teeth, rather than in spaces where teeth never formed. Understanding these distinctions is crucial when diagnosing dental cysts based on their location and origin.
